What happens to the temperature of a substance that is an endothermic reaction?
It will decrease as heat is removed from the environment and added to the products of the reaction.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
What is endothermic use in a sentence?
Endothermic means a temperature under a surface and is used in a number of instances, most notably medicine where it is used to describe a temperature under the skin, and geology where it can be used to describe the temperature under the suface of a planet, therefore a use of endothermic in a sentence could be;"The endothermic temperature of the planet was greater than that of it's surface."
How does a temperature increase cause the rate of a reaction to increase increase?
It increases the kinetic energy of the molecules (APEX)
Is a snail endothermic or exothermic?
A reptile maintains an internal temperature by using exothermic methods of controlling its body temperature.
Effects of temperature and pressure on exothermic and endothermic reaction?
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
How does temperature affect solubility of a substance which involves endothermic process in forming a solution?
endothermic substances absorb energy when dissolved. Therefore supplying energy(heat) externally will increase the solubility.
How does temperature affects the rate of industrial reaction?
It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
What happens to the temperature of a substance that is an endothermic reaction?
It will decrease as heat is removed from the environment and added to the products of the reaction.
When a reaction is endothermic what usually happens to the temperature overtime?
The temperature will decrease. Endothermic reactions absorb heat engery, so the temperature of the suroundings will drop.
Is an eagle endothermic?
Yes, owls are endothermic as they maintain a stable body temperature.
Is an elephant endothermic or ectothermic?
A horse is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
What happens to the reaction 2NO2 N2O4 57.2 kJ when the temperature of the reaction is increased?
This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
Are cougar's endothermic or endothermic?
A cougar is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
